Pulverized samples of a Cambrian schist from Slemmestad by Oslofjorden and a coarse-grained marble from Storforshei, Mo i Rana, were extracted with a mixture of benzene and methanol. Qualitative analyses of the upconcentrated extracts were made with a gas chromatograph connected to a mass spectrometer; the subsequent quantitative analyses were made with a gas chromatograph. In the two samples about 25 organic compounds were detected, their concentrations varying about 1 p.p.m.
